  2. 1. Microphase Separated Cation Conducting Polymers : Design, Synthesis, and Properties

    Author : Hannes Nederstedt; Centrum för analys och syntes; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polymer; Litiumbatteri; Mikrofasseparering; Bränslceller; Elektrolyt; Polymerelektrolyt; Polymera bränslecellsmembran; Polymer electrolyte fuel cells; Polymer electrolyte; Polymer electrolyte membrane; Microphase separation; Lithium battery; Polymer; Fuel cell; Proton exchange membrane PEM ;

    Abstract : This thesis describes the synthesis and properties of five different cation conducting polymer systems. These systems were designed so that the polymers would be able to microphase separate into distinct phases with one phase for mechanical strength and one for ionic conductivity. READ MORE

  4. 2. Structural Lithium Ion Battery Electrolytes

    Author : Niklas Ihrner; Mats Johansson; Daniel Brandell; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structural batteries; Structural battery electrolyte; Lithium ion batteries; Polymerization induced phase separation; Carbon fibers; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : A major challenge in the electrification of vehicles in the transport industry is that batteries are heavy, which reduces their effectiveness in mobile applications. A solution to this is structural batteries, which are batteries that can carry mechanical load while simultaneously storing energy. READ MORE
